To all whom t may concern.'

Be it known that I, ISRAEL M. GRIMM, citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare that the following is a full, clear, and exact description o-f the invention, which will enable others skilled in the art to which it appertains to A.make and use the same. Y

This invention relates to that class of devices known as sash fasteners or sash locks.

The invention relates more particularly to a fastener or lock as applied to windows or sashes of railway coaches.

The object of the invention is to provide l an exceedingly strong and well made sash fastener particularly adapted for windows of a railway coach, which, in addition to having a series of supports to carry and form the guides for the usual sliding bolt, is provided with an easily operated pivoted finger-piece to operate said bolt, said fingerpiece carrying an integral curved or arched guard to overlie an arched wall through which the finger-piece extends, and which is described from the pivot of said finger-piece,

so that foreign matter cannot drop into the` |interior of the fastener nor'be pushed in by those traveling in said coach and which might otherwise render the fastener useless until removed and cleaned.

The invention also relates to certain details o-f construction all of which will be pointed out herein'aided by the accompanying drawing in which,

Figure l shows the lock or fastener in perspective. Fig. 2 is a transverse sectional elevation of the same. Fig. 3 shows a finger-piece in perspective. Fig. 4 is a rear elevation of the lock or fastener. Fig. 5 is a plan of the same, and Fig. 6 is a plan of the locking bolt. Y

The body of the lock is indicated by the reference character A. It is provided with a depending flange B at its lower portion provided with the usual screw holes C, and

it is provided at other places with ears D provided with suitable screw holes by which the lock may be fastened in position on the sash. In addition, on its rear side the body has one or more projections or studs E which when the lock is attached to the sash are let into holes in said sash in which they will'snugly t.

the body A through all three of which the 1 locking bolt K extends. It is observed that the said bolt is of large diameter where it extends through the walls L and J but is reduced in size where it extends through the wall M receiving on its reduced portion a spring N which holds the bolt normally in its outermost position as its locking position.

That part kof the bolt extending through the walls L, J, is made of large size in order that it will'not easily be bent by striking upon the projection of the usual rack-bar (not shown) .secured to the window-frame in case the window falls, and in addition to the size of the bolt I provide the additional intermediate wall .I so that it will be practically impossible for the bolt to be arched, there being the three points of support or bearing, said bolt having a snug sliding fit in the several walls or supports.

O is the finger-piece pivoted at its lower end on a stud I), being held thereon by any suitable means such as a split-key Q. Said finger-piece extends through a slot R in the upper 'and top wall of the body in position to be grasped and pressure being applied thereto by the thumb. The bolt K is provided with a notch S, the opposite walls of which are formed so as to provide Contact points for opposite edges of the said fingerpiece 0.

Preferably the upper wall of the body is thickened and the top 4surface is rounded or curved being described from the pivot of the said finger-piece. The latter is provided with an extension T whose under surface is described from the same point as the curve of the top surface of the described thickened portion. The extended part T normally overlies the slot R so that dirt that would tend to prevent a free operation of the bolt cannot enter the slot and ll up the recess H. The extent of the curved surface of the body is such as to permit the extension T to have free movement in the full swing of the latch, the extension fully cov ering the slot R. If desired the device may be so constructed that the said slot R can be covered in either extreme position of the linger-piece so that mischievous persons will not be able to push objects into the slot and prevent the operation of the bolt. Not only this, but the screws for fastening the lock to the window become loosened by the severe jar requiring the loclr to be reset if indeed it can be used.

In my device the locking bolt is supported at three places, that is to say, in all three walls L, J, M of the body so that it is practically impossible to bend said bolt by the most severe jar or blow. Again, the projection or studs E shown, or as many more as it may be the desire to use, may be set into the wood and absolutely prevent the lock from becoming loosened and the screws used to secure it in place are not subjected to strains incident to the falling of the sash by the bolt striking projecting parts.

In addition to the disadvantages already named in connection with the usual forms of sash lock of the type described is the further one that few, if any of them, provide a suflicient grasp for the fingers to assist in lifting the sash.V In the majority of instances the sash due to the twisting and straining of the car is prevented from being easily raised and the small grasping portion ordinarily furnished does not afford the proper finger hold. This is an important feature in my lock, and, combined with the position of the finger-piece at the top of the body, furnishes a means by which the locking bolt can be withdrawn with ease and the window raised without effort. That is to say, in grasping the lock the four fingers on being placed beneath the lock naturally calls for a gripping of the same by bringing the thumb ,down upon the top and the thumb in meeting the linger-piece moves the same almost automatically and the bolt is withdrawn.

I-Iaving thus described my invention, I claim 1. As an article of manufacture, a recessed body grooved exteriorly beneath its lower edge, a locking bolt slidably mounted in said body, a finger-piece operatively engaging the bolt and extending substantially perpendicular to the line of movement of said bolt and extending outward through the top wall of the body and pivoted at its inner end to said body inward from the said wall, the locking bolt lying between the described top wall and the pivot of said finger-piece, that part of the wall through which the finger-piece extends being outwardly curved concentrically to the pivot of the latter, an extension carried by the finger-piece also curved concentrically to the pivot and adapted to overlie the opening in the wall through which the fingen piece extends and to close said opening in any position of said finger-piece, and a spring arranged to hold the bolt normally and elastically in its locking position and to hold the linger-piece elastically at one of its extreme positions.

2. As an article of manufacture, a hollow body closed at its outer or front Side and having integral lugs extending from its opposite side, a member slidably mounted in said body, a spring holding the member in one of its extreme positions, a member pivoted at one end within the body and lying substantially perpendicular to the line of movement of the iirst member and operatively engaging it, the second described member extending through and outside of one of the walls of the body, there being a slot in said wall through which the said second member extends, the outer surface of said wall at said slot being curved concentrically to the pivo-t of the second member, and an extension on the latter overlying and conforming to the curve of the wall and covering the slo-t.

In testimony whereof I aiiix my signature, in presence of two witnesses.
